Calculate the dynamic viscosity of an oil, which is used for lubrication between a square plate of size 0.8m×0.8 m and an inclined plane with angle of inclination 30°. The weight of the square plate is 300N and its slides down on the inclined plane with a uniform velocity of 0.3m/s. The thickness of oil film is 1.5mm.
